SPLASH GUARD FOR MACHINE TOOLS AND LIKE PURPOSES Filed Sept. 6, 1957 I lll l IIILITIIIIII l.

Unite States Patent SPLASH GUARD FOR MACHINE TOOLS AND LIKE PURPOSES The present invention generally relates to splash guard devices, and more particularly to splash guards adapted for use on machine tools or the like, such as grinders, lathes, lubricating fluid to the tool proper or to the work being machined, and in which the splash guard comprises a transparent panel which is movable from an active to an inactive position in order to enable work pieces to be positioned and removed, respectively.

A primary object of the present invention is to provide a splash guard of the kind referred to which is bodily displaceable from its operative position.

Another object of the invention is to provide a splash guard of the kind stated having its movable panel ,so disposed and arranged as to enable the machine operation to be observed continuously without the necessity of removing thesplash guard from its operative position.

Another object of the invention is to provide a splash guard of the kind stated in which the splash guard is adjustable into various positions to adapt the same in accordance with various requirements.

A further object of the invention is to provide a splash guard device of the kind referred to which is extremely simple to handle in operation.

For the objects thus stated, in accordance with the present invention, a splash guard device of the kind referred to is further characterized by comprising first guiding means for two oppositely disposed edges of said transparent panel, this panel being substantially rectangular in shape, said guiding means extending at right angles to the longitudinal axis of said machine tool whereby said panel is displaceable along a path extending substantially transversely relative to said axis, and said guiding means being further carried by two opposite side members of a frame structure which is so arranged as to be displaceable in a direction parallel to the longitudinal axis etc., having means for supplying a cooling and/ or of said machine tool and to be locatable in various positions of displacement, said frame structure being thus displaceable along second guiding means extending in spaced parallel relation to the longitudinal axis of said machine tool, one of said second guiding means provid ing pivot means about which said frame structure is swingably mounted to enable said frame structure together with said movable panel to be swung out of its operative position.

In a preferred form of the splash guard device as stated in the preceding paragraph, said second guiding means are in the form of rods which are circular in cross-section.

Further features and advantages of the present invention will become apparent from the following description thereof in conjunction with the accompanying drawing which illustrates a preferred embodiment of the invention, and in which:

Fig. 1 is a front elevation of the device, and

Fig. 2 is a left-hand end elevation of the splash guard novel splash guard shown in Fig. 1, but with the transparent panel thereof moved into its inactive position.

Referring now to the drawing more meral 1 designates a portion of a machine tool which is diagrammatically indicated inpart only, the remainder: of the machine tool-which is assumed-1n the presentcase to be a grinding machinebeing completely omitted for simplicity of illustration since the machine proper forms no part of the present invention. Numerals 2 and 3 designate two panels of which one, viz; the panel 2 is a sheet-metal plate which extends at an angle up-,

ward and outward from thefront'edge portion of the table 1, whereas the other panel 3 is transparent and may conveniently be made of shatterless glass or any suitable other material. The first-mentioned panel 2'at its lower edge engages a longitudinal groove 4 formed in said edge portion of the table 1, and at its upper edge said panel 2 is connected with the remainder of the splash guard. The last-mentioned connection may be either detach-able or rigid.

The transparent panel 3 is surrounded by a closed metal.

frame 5 and is substantially rectangular in shape, two oppositely] disposed edges ofthe panel 3 co-operating with corresponding guides 6 extending substantially at right angles to the longitudinal direction of the table 1,'

the non-illustrated longitudinalaxis of the'machine tool. The guides being parallel to the last mentioned direction. 6 which may be channel-shaped in cross-section andwith which the panel- 3 co-operates through the intermediary of the closed frame 5, form two oppositely disposed side members of a substantially rectangular frame structure'- 7 which is displaceable in the longitudinal direction of the ing members for this displacement. These rods 8, 9, extending in spaced parallel relation to the longitudinal direction of the table 1, are carried by upright members 10, 11' the foot ends of which are secured to cross-members 12 which are suitably detacha'bly connected with the table 1 and extend transversely across the top of this table. 1

In its active position as shown in Fig. 1, the panel 3 is retained against displacement from this position by a spring-loaded latch 13 engaging a shoulder 14 provided on the lower member of the closed frame 5 of the transparent panel 3. The latch 13 is fulcrumed at the lower member of the frame structure 7 and is formed by a double-armed lever of which one arm forms the latch proper while the other arm is acted on by a compression coil spring 15 which urges the latch towards its latching position. The transparent panel 3 is actuated by two springs (not shown) which are disposed within individual tubes 16 to which one end of the respective springs is secured. The opposite end of each such spring is connected to a wire 17 which runs about a pulley 18 and is secured to the frame 5 of the transparent panel 3. The last-mentioned two springs are tension coil springs which urge the panel 3 upward towards the upper member of the frame structure 7, i. e. away from its active position shown in Fig. 1. The wire pulleys 18 are journalled on the rod 8 which is formed as an axle of circular crosssection and serves as a guiding member for the sliding frame structure 7.

The frame structure 7 is provided at its upper longitudinally extending member with lugs 19 apertured for the rod or axle 8, whereby, the frame structure 7, together with the transparent panel 3 and possibly the panel 2 also, is swingable about the axle 8 so as to enable the splash guard to be moved bodily away from its operative position. To enable this, the rod 9 may be retractable, or alternatively it may be so devised as to accompany the splash guard in its angular movement about the axle 8.

The mode of operation of the splash guard described Patented 'Jan. 6,1959;

specifically, nu-

table 1 by being slidable along rods 8, 9 serving as guidhereinbefore would be obvious from the description thus furnished and from the accompanying drawing, and it need only be mentioned here that, owing to the presence of the transparent panel 3, it will be possible to observe and check the progress-of the machining being carried out, without the necessityfof moving the splash guard away from its operating'position. Further, it will be possible to adjustthe splash guard into various positions in order to adapt the same to various practical requirements; In addition, the operation and handling of the splash guard is seen to be extremely sirnple.

' Itwill be obvious to anyone skilled in the art the structural realization of the present invention is by no means restricted to the sole embodiment described hereinbefore and as illustrated in the accompanying drawing, but that the same is susceptible of variations and modifications in its details without departing from its scope.
